Standard Filtration Modes FØ - F3
Heating in either of these modes (FØ - F3) is automatically controlled by the water temperature. If the
hot tub water drops 2ºF (1.2ºC) below the temperature setpoint, the heater will turn on with the circula-
tion pump. Both remain on until the water temperature rises to the temperature setpoint, then the heater
will turn off. Refer to the options below:
FØ

Economy Filtration Modes F4 - F6
In any economy mode (F4 - F6), the control panel’s digital timer circuit determines when each lter
cycle takes place. The heater will only operate while a lter cycle is running. The heater will not operate
when either Jets button is pressed to manually cancel an active lter cycle or to activate the main jet
pump between lter cycles. Refer to the options below:
F4

Lockout Modes L1 - L2
Additional modes (L1 - L2) are special modes designed for servicing/cleaning. Refer to the options
below:
L1
L2
Lock Out (disables all hot tub functions to permit lter cleaning or other maintenance) - If the hot
tub is heating when the system is put into lockout mode, the heater will immediately shut off and
the circulation pump will cycle water for 30 seconds to cool the heater element, then shut off.
Lock Mode (disables the jets and light buttons to prevent unauthorized use of the hot tub) - The
lter cycles and heater will continue to operate as programmed in this mode. Example: The “F3”
lter cycle was enabled prior to choosing the lock mode. The hot tub continues to perform lter
cycle “F3” until lock mode is cancelled, allowing another lter cycle to be selected.
The temperature display ashes when either Lock Out Mode is enabled.
